High-grade soft tissue sarcoma, often near large joints of extremities (knee, ankle). Affects adolescents and young adults (15–40 years). Histology: biphasic (epithelial + spindle cells) or monophasic; SYT-SSX fusion gene (t[X;18]). Imaging: calcification may be seen on X-ray; MRI shows heterogeneous mass. Treatment: wide excision with radiotherapy; chemotherapy (ifosfamide, doxorubicin) improves survival in advanced cases.
